Abstract: Good home-school co-education is conducive to promoting the healthy growth of children, but also conducive to the family and school to achieve educational goals. Home-school education must be based on the home-school interaction, the perspective of home-school interaction, through the micro practice process of home-school education, the lack of focus of attention, the lack of group cohesion and emotional resistance. Based on this, the school should innovate the way of co-education to enhance the "presence", create the co-education symbol under the value of "life oriented", generate the focus, and promote the emotional sharing and stimulate the co-education on the basis of condensing the group spirit.
